This is really sad, he seemed like a really helpful and nice person. Maybe in the next universe, we will find him...
A few days ago the book translated to English arrived. I immediately thought of marcus.This news truly shocks me. Although I didn't really engage in much discussion with him, he seemed well informed on a variety of physics topics and recent pre-print's and their popularity. He was also the person who guided me in the direction of a book that was in Italian, and soon to be published in English. That book will serve me a reminder of marcus. May he rest in peace.
"will be"?Marcus will be greatly missed.
